Risky Cash-Out Refis

Posted on by

Anil Kumar of the Dallas Fed has posted Do Restrictions on Home Equity Extraction Contribute to Lower Mortgage Defaults? Evidence from a Policy Discontinuity at the Texas’ Border to SSRN.  The abstract reads

Given that excessive borrowing helped precipitate the housing crisis, a key component of a policy agenda to prevent future meltdowns is effective regulation to curb unaffordable mortgage debt. Texas is the only US state that limits home equity borrowing to 80 percent of home value. Anecdotal reports have long suggested that home equity restrictions shielded Texas homeowners from the worst of the subprime mortgage crisis. But there is, as yet, no formal empirical investigation of these restrictions’ role in curbing mortgage default. This paper is the first to empirically estimate the impact of Texas home equity restrictions on mortgage default using individual and loan level data from three different sources. The paper exploits the policy discontinuity around Texas’ interstate borders induced by the home equity restrictions to identify the causal effect of home equity extraction on mortgage default in a border discontinuity design framework. The paper finds that limits on home equity borrowing in Texas lowered the likelihood of mortgage default by about 2 percentage points with a significantly larger impact on mortgage borrowers in the bottom quartile of the credit score distribution. Estimated default hazards for mortgages within 50 to 100 miles of the Texas’ border decline sharply as one crosses into Texas. Overall, the paper finds evidence that Texas’ home equity restrictions exert a robust negative impact on mortgage default.

This is a really important paper asking a really important question.  If its findings are confirmed, it brings us back to that age-old question of paternalism in consumer financial protection: should we limit a consumer’s choice if that choice is consistently shown to have harmful effects?  I am not sure where I come down in this particular case, but I wonder if some version of Quercia et al.‘s benefit ratio could help measure the costs and benefits of such a rule. The benefit ratio compares “the percent reduction in the number of defaults to the percent reduction in the number of borrowers who would have access to [a certain type of] mortgages.” (20) I am not sure whether access to cash out refi mortgages is of the same import as purchase mortgages or even plain old refis, but the concept of the benefit ratio might still make sense in this context.

Lifting a Shadow from Qualified Residential Mortgages

Posted on by

The self-named Shadow Financial Regulatory Committee of the American Enterprise Institute has issued a statement on The New Qualified Residential Mortgage Rule Proposal.  The Shadow Committee argues that agencies promulgating the newest version of the QRM rule

completely abandoned the Act’s requirement for a separate high-quality QRM. Instead, they proposed a QRM that was essentially the equivalent of the QM. This not only violated the congressional intent and nullified the retainage, but it pushed the US mortgage system back toward the very policies that fed the housing bubble, the mortgage meltdown and the financial crisis. It responds to those want the mortgage finance system to make mortgage credit widely available, but it ignores the need for a stable system that will avoid a future crisis. (2)

This is not fully accurate. The QRM proposal does not violate congressional intent because Congress merely stated that the QRM be “no broader” than the QM. (Dodd-Frank Act Section 941) There is also a fair amount of fear-mongering here because the Shadow Committee does not propose how we can responsibly balance credit availability with systemic stability.

Nonetheless, the Shadow Committee is right to note that the rules governing mortgages must balance a number of competing goals.
When the proposed rule was released, I had written that it should incorporate a “benefit ratio” which

compares “the percent reduction in the number of defaults to the percent reduction in the number of borrowers who would have access to QRM mortgages.” (20) A metric of this sort would go a long way to ensuring that there is transparency for homeowners as to the likelihood that they can not only get a mortgage but also pay it off and keep their homes.

A benefit ratio would not only help ensure that homeowners received sustainable mortgages, but it would also address the systemic concerns raised by the Shadow Committee. This is because the benefit ratio would protect lenders from their own worse instincts as they lower their underwriting standards in pursuit of increased market share in a booming market.

Benefit Ratios for Qualified Residential Mortgages

As I had noted previously,

the long awaited Proposed Rule that addresses the definition of Qualified Residential Mortgages has finally been released, with comments due by October 30th. The Proposed Rule’s preferred definition of a QRM is the same as a Qualified Mortgage. There is going to be a lot of comments on this proposed rule because it indicates that a QRM will not require a down payment. This is a far cry from the 20 percent down payment required by the previous proposed rule (the 20011 Proposed Rule).

The Proposed Rule notes that in “developing the definition of a QRM in the original proposal,” the six agencies [OCC, FRS, FDIC, FHFA, SEC and HUD] responsible for it “articulated several goals and principles.” (250)

First, the agencies stated that QRMs should be of very high credit quality, given that Congress exempted QRMs completely from the credit risk retention requirements.

Second, the agencies recognized that setting fixed underwriting rules to define a QRM could exclude many mortgages to creditworthy borrowers. In this regard, the agencies recognized that a trade-off exists between the lower implementation and regulatory costs of providing fixed and simple eligibility requirements and the lower probability of default attendant to requirements that incorporate detailed and compensating underwriting factors.

Fourth, the agencies sought to implement standards that would be transparent and verifiable to participants in the market.” (250)

After reviewing the comments to the 2011 Proposed Rule, the agencies concluded that “a QRM definition that aligns with the definition of a QM meets the statutory goals and directive of section 15G of the Exchange Act to limit credit risk, preserves access to affordable credit, and facilitates compliance.” (256)

I was somewhat disturbed, however, by the following passage. The agencies are

concerned about the prospect of imposing further constraints on mortgage credit availability at this time, especially as such constraints might disproportionately affect groups that have historically been disadvantaged in the mortgage market, such as lower-income, minority, or first-time homebuyers. (263)

While it is important to make residential credit broadly available, the agencies will be doing borrowers no favors if their loans are not sustainable and they end up in default or foreclosure. The agencies should come up with a metric that balances responsible underwriting with access to credit and apply that metric to the definition of a QRM.

Quercia et al. have developed one such metric, which they refer to as a “benefit ratio.” The benefit ratio compares “the percent reduction in the number of defaults to the percent reduction in the number of borrowers who would have access to QRM mortgages.” (20) A metric of this sort would go a long way to ensuring that there is transparency for homeowners as to the likelihood that they can not only get a mortgage but also pay it off and keep their homes.
